FRANK A. LAKE, OF CASSOPOLIS, MICHIGAN. BALING-PRESS.

Application filed March 9 To all whom t may concern,.-

Be it known that I, FRANK A. LAKE, a citizen of the United States,residing at Cassopolis, in the county of Cass and State of Michigan,have invented certain new and useful Improvements in Ealing-Presses;andIdo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to baling-presses, and particularly to presses inwhich a reciprocating plunger is employed to compress the material inthe bale-chamber.

The invention will be fully described in the following specification,reference being had to the accompanying drawings, in which- Figure 1 isa perspective view of a balingpress embodying my invention. Fig. 2 is aside elevation of the bale-chamber and the feed mechanism. Fig. 3 is avertical transverse section on the line 3 3 of Fig. 6. Fig. 4 is avertical transverse section on the line 4 4 of Fig. 2. Fig. 5 is avertical longitudinal section through the bale-chamber. Fig. 6 is a viewsimilar to Fig.. 2, showing the feed mechanism in adierent position.Figs. 7 and 8 are plan views of a double-faced cam and other devices forreciprocating the plunger, the parts being shown in different positions.Fig. 9 is a detached detail. Fig. 10 is a perspective view of theplunger and its pitman. Fig. 11 is atop plan view of the rear portion ofthe contracting chamber, and Fig. 12 is a sectional view of the same onthe line 12 12 of Fig. 11.

That portion of the bale-chamber within which the plunger reciprocatesis indicated by 1 and has solid sides and bottom, while the top isprovided with an opening forming a feed-throat for the material to bebaled. EX- tending upwardly from the front and rear ends of the openinginthe top of the box 1 are two hinged plates 2 and 3, and a series offingers 4 extend upwardly from the sides, and these plates and fingersform a feed-hopper for the bale-chamber. The fingers on one side aresecured to a shaft 5 and on the other side to a shaft 6, both shaftsbeing supported to turn in suitable bearings on the side of the boX 1for a purpose to be hereinafter explained. The shaft 5 is provided witha crank-arm 7 at its end adjacent the plate 2, and the shaft 6 has acrank-arm 8 at the corresponding end, and these arms are connected by alink 9. The crank-arms are so arranged that when the Specification ofLetters Patent.

shaft 5 is rocked in one direction the shaft 6 will rock in the oppositedirection, thereby causing the opposing sets of fingers 4 to move towardor away from each other. In Fig. 3 these sets of fingers are shown indotted lines moved inwardly toward each other with their outer endscrossed, and the fingers are moved to this position for the purpose ofpressing the material in the hopper down into the balechamber. In orderto rock the shaft 5, I provide it with another crank-arm 10, which maybe connected to it at any point in its length, and this arm 10 isconnected by a link 11 to one end of a lever 12, pivoted between itsends on a stud 13, projecting from the side of the bale-chamber. Theother end of the lever 12 is connected to a rod 14, which is providednear its forward free end with a shoulder 15. That part of the rod inadvance of the shoulder is beveled, as indicated at 16, (see Fig. 6,)and its forward end rests upon a bracket or loop 17, secured to a xedpart ofthe machine. (See Figs. 1, 2, and 6.)

It is desirable to operate the fingers 4 during the forward ornon-compressing movement ofthe plunger 20, and in order to do this Iprovide the plunger-pitman 21 with a lug 22, adapted to engage theshoulder 1 5. When the pitman is moved forward, the lug 22 will engagethe shoulder 15 on the rod 14 and pull the latter forward, and therebymove the fingers 4 to the position shown in Fig. 3, dotted lines. As therod moves forward its inclined or beveled portion 16 will ride up on thebracket or loop 17, and thereby disengage the shoulder 15 from the lug22, and aspring 23, which acts on the lever 12, will at once return thefingers 4 to normal position. The inward movement of the fingers 4gathers the hay or straw that may be in the hopper and pushes it partlythrough the feed-throat into the chamber; but it is necessary to stillfurther press the material down into the chamber, and to accomplish thisI provide a second set of fingers, which are indicated by 24. As shownin the drawings, there are two of these fingers 24 on each side of thebale-chamber; but there may be more, if desired. The fingers 24 on oneside of the chamber are fixed at their lower ends on a shaft 25 andthoseon the other side to a shaft` 26, these shafts being supported toturn in suitable bearings on the sides of the chamber, and they areconnected to turn together by crankarms 27 and 28 and link 29 in thesame manner as shafts 5 and 6. In order to rock these IOO IIO

shafts 25 and 26, I provide shaft 25 with another crank-arm 30, which isconnected by a link 31 to one arm 32 of a bell-crank lever pivoted on astud projecting from the side of the chamber, in this case the stud 13,upon which level 12 is pivoted. The other arm 33 of the bell-crank leveris connected to a rod 34, provided with a shoulder and inclined portion36, and the forward free end of this rod also rests upon the loop orbracket 17. The forward portions of the levers 14 and 34 are constructedsubstantially alike; but the shoulder 35 is farther away from thebalechamber than the shoulder 15, and the parts are so arranged that thelug 22 will engage the shoulder 35 just after the shoulder 15 has beendisengaged from said lug.

It will be observed that the lower ends of the fingers 24 are much lowerdown than the lower ends of the fingers 4 and also that their upper endsare curved outwardly from the bale-chamber. The sides of the chamber areslotted, as indicated by 37, to permit the iingers 24 to move inwardlytoward each other, and the several parts are so arranged that pull bythe rod 34 will cause the fingers 24 to move through an arc of aboutninety degrees to the position shown in dotted lines in Fig. 4. As soonas the inclined portion 36 rides up on the loop 17 and releases theshoulder 35 from the lug 22 a spring 38, which engages a projection onthe link 31, will return the parts to normal position.

As before stated, the lingers4 will operate before the fingers 24 andboth will operate during the last portion of the outward movement of theplunger, the lug 22 and loop 17 being so arranged that they will contactjust as the outward movement of the plunger is completed. The fingers 4gather the hay or straw which is in the hopper, fold it over, and pressit partially through the feed-throat to the chamber, and as soon asthese 'lingers are released the lingers 24 will be moved inwardly, stillfurther fold the material, and will force the material down into thechamber, compress it in a vertical direction, and then move back tonormal position just before the plunger begins its inward or compressingstroke.

It is of course necessary to provide some means for preventing thematerial passing into the bale-chamber behind the plunger, and for thispurposeI provide afolding apron 39, made in two sections hingedtogether, one section being rigidly connected to the plunger and theother loosely connected to one end of a link 40, the othervend of whichis connected to the plate 2. The bale-chamber is provided with the usualside checks 41 and top check 42.

From the rear of the bale-chamber extends the usual contracting chamber43. This is formed by four angle-bars 44, extending from and formingcombinations of the four corners of the bale-chamber 1. These angle-barsare rigidly connected at one end to the chamber and their outer ends areconnected to two bars 45, and the bars 45 are adjustably connectedtogether at their upper and lower ends by spring tie-rods 46. Theangle-bars on one side of the chamber may thus be moved toward or awayfrom those on the other side.

The top of the chamber 43 is preferably a solid plate 47, formingacontinuation of the top of the bale -chamber. This plate lies looselybetween the top angle-bars and is of less width than the top of thebale-chamber in order to permit the adjustment of the sides of thecontracting chamber toward each other. The sides of the contractingchamber are preferably made of slats 48, connected at one end to thesides of the bale-chamber and at their other ends to the bars 45. Thebottom will also consist of one or more slats 49, connected at one endto the bottom of the bale-chamber and loosely supported at their outerend on the bottom tie-rod 46.

I will now describe the mechanism for actuating the plunger. indicates areach rigidly connected at its rear end to the balechamber and pivotallyconnected at its forward end to the axle 51 and arch 52. Theplungerpitman 21 is provided at its outer end with a head 53, providedwith spaced ears 54, between which a roller 55 is journaled. (See Fig.10.) The head is also provided with two guiderollers 56, mounted on avertical axis, one of said rollers engaging one side of the reach andthe other engaging one side of a bar 57, rigidly connected to the reachand extending above it. The head is also provided with a guide-roller58, mounted on a horizontal axis and vengaging a horizontal flange 57 onbar 57. The pitmau is thus guided in its reciprocating movements. 60 isan S-shaped doublefaced cam journaled between the end of the reach 50and the arch 52 and provided with a bar 61 on the upper end of itsjournal, to one end of which a draft-pole 62 is connected. A

brace-rod 63 is connected to the other end ofy the bar 61 and to theother end of the draftpole 62. A swingletree 64 is connected to theouter end of the pole 62 and a horse is intended to be hitched theretoand travel around in a circle in order to revolve the cam 60. The outercurved surfaces 65 of the cam are adapted to alternately engage theroller 55 in the head of the pitman, and thereby move the plungerrearwardly to compress twice in every revolution of the cam. In order tomove the plunger forward, I provide a lever 66, pivoted at one end uponthe reach 50, Figs. 7, 8, and 9, and a link 67 connects the other end ofthe lever to the pitman 21. Adjacent to its pivot the lever is providedwith a lug 68, with which lugs 69 on frame 70 are adapted to engage, theframes being rigidly connected to the cams. The parts are so arrangedthat just as one curved surface 65 of the cam disengages IOO IIO

the roller 55 one of the lugs 69 will engage lug 68, and as the camcontinues its rotation the lever 66 will be moved from the positionshown in Fig. 7 to that shown in Fig. 8, which results in moving theplunger forward. The lug 69 then moves out of engagement with lug 68,and the other curved face 65 of the cam is just engaged with the roller55. It will be seen, therefore, that the pitman is reciprocated twiceduring each complete revolution of the cam.

Having described the invention, without limiting-myself to the precisedetails of combination described, I claim-- 1. In a baling-press, thecombination with the bale-chamber, reciprocatory plunger and its pitman,of a hopper having rock-shafts journaled at opposite sides thereof, aseries of fingers rigidly secu red to said shafts and forming two sidesof the hopper, a lug on the pitman, a rod having a lug to be engaged bythat on the pitman to move the two series of fingers toward each other,lever-and-link connections between the rod and said shafts, and a springfor moving the two series of fingers away from each other substantiallyas and for the purpose specified.

2. In a baling-press, the combination of the bale-chamber, plunger andits pitman, of a hopper having two opposite sides formed of series ofpivotally-supported fingers, a second series of pivotally-supportedfingers on opposite sides of the bale-chamber below the firstnamedfingers` means operated by the pitman for moving the fingers of thefirst series toward each other, and means operated by the pitman formoving the fingers of the second series toward each other after themovement of the rSt.

3. The combination with the bale-chamber of a baling-press, of afeed-hopper communicating with the chamber, two series of fingers onopposite sides of the hopper above the feedthroat of the chamber, twoseries of fingers on opposite sides of the chamber below thefeed-throat, means for first moving the upper series of fingers towardeach other, and means for moving the lower series of fingers toward eachother after the movement of the upper series.

4. In a baling-press, the combination with the bale-chamber, pitman andplunger, of a feed-hopper, rock-shafts supported on opposite sides ofthe hopper, series of fingers secured to said rock-shafts and formingtwo sides of the hopper, crank-arms on the shafts, a link connectingsaid crank-arms, a second crankarm on one of the shafts, a lever pivotedbetween its ends, a link connecting the second crank-arm and one end ofthe lever, a rod connected to the other end of the lever, said rodhaving a shoulder, a lug on the pitman to engage said shoulder, meansfor disengaging the lug and shoulder after a predetermined movement ofthe pitman, and a spring for returning the fingers to normal position.

5. In a baling-press, the combination of the plunger, pitman, and abale-chamber having slots in two opposite sides, a rock-shaft supportedon each of said sides, fingers rigidly connected to said shafts oppositetheA slots, crank-arms on the shafts, a link connecting said arms, asecond crank-arm on one of the shafts, a pivoted bell-crank lever, alink connecting said second crank-arm with one arm of the bell-cranklever, a rod connected to the other arm of the bell-crank lever andhaving a shoulder, a lug on the pitm'an to engage said shoulder, meansfor disengaging the lug and shoulder after a predetermined movement ofthe pitman, and a spring to return the fingers to. normal position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
